Ebay
Free Ebay Cool Research Tool
Another one of those cool web2.0 website but gives interesting statistics. Even though I am not into eBay, this tool looks pretty cool and might be great for keyword research and for locating great niches :
Website : www.terapeak.com
They have paid research services too like finding out when is the best time to sell, ebay sellers’ information, finding the hottest products etc.
I am going to see what I can dig out from this site. And the best part it is for free. Now who doesn’t like free?
